I use River3 to read RSS

That's a site that's maintained by River3, which is a Dropbox-based news aggregator. I've been working on it in my spare time while we've been shipping Fargo and Trex. The reason I can do that is that it's a vast simplification of the previous river product, River2.

First, there's no UI. All input comes in through a Dropbox folder. And all output is published to the same folder.

The input is this: a set of OPML reading lists, and a template.

The output: A folder with HTML files, one with logs, and another with JSON files that can plug into other river displays if needed. (We will have this in Fargo, soon.)

The output folder is optionally mirrored on S3, so you don't have to fuss with how to make things public.

The app runs in the OPML Editor, so it can run on Windows or Mac. This is not a Small Picture product, it's just a thing I've been working on, on the side.

It's pretty easy to set up, through the normal server configuration system in the OPML Editor environment. I know it's weird that an editor is also a server. But that's the way these things evolve. Servers everywhere.

I haven't made this app available to others, but if I do, it will be through the Frontier-user list. It won't be open source, but it will be free to use for whatever you like.
